A resident walks in a street after a second earthquake hit southwestern Japan, in Mashiki, Kumamoto Prefecture, southwestern Japan, 16 April 2016. The 7.3 magnitude earthquake that struck southwestern Japan early 16 April has now left 19 dead and a thousand injured, in a region where a day before another powerful quake claimed ten lives. The latest quake occurred on Kyushu island's western coastal prefecture of Kumamoto, with an epicenter located about 10 kilometers deep. EPA/KIMIMASA MAYAMA Companies including Sony 6758.T and TSMC 2330.TW, the world’s largest contract chipmaker, have plants in the area of the quake.
A Sony spokesperson said the company was checking the situation. TSMC did not immediately respond to a request for comment.
The Japanese government issued emergency earthquake warnings for Kumamoto, Nagasaki, Kagoshima, Fukuoka, Saga, Oita, and Miyazaki prefectures, all on Japan’s southern Kyushu island. A tsunami warning for a wave measuring 1 m (3.28 feet) was issued after the earthquake, the Japan Meteorological Agency said.
Japan is one of the world’s most earthquake-prone countries, with a tremor occurring at least every five minutes. Located along the “Ring of Fire” of volcanoes and oceanic trenches partly encircling the Pacific Basin, Japan accounts for about 20% of the world’s earthquakes of magnitude 6.0 or more.
A massive earthquake in Kumamoto 10 years ago killed 275 people and injured a further 2,739, according to an official count.
Kyushu Electric Power said about 40,000 homes had lost power as a result of the quake, while railway company JR Kyushu said that it had suspended services, including its high-speed bullet trains.
There were no irregularities reported at the nuclear power stations in the area, Japan’s nuclear regulation authority said.
